Claims. (01. 1464) The invention relates to devices for cutting a bearing member 11 in which is slidably mountthe grains from ears of corn, and has for its ed a rack bar 12 having a flanged plunger 13 object the provision of a machine of the type secured to its lower end to engage the top of the referred to that will effectively remove the grains ear of corn. The rack bar 12 and plunger 13 from the corn cob while being formed through are actuated by means of a pinion 14 keyed to a cutting element and depositing the grains in a shaft 15, and 16 indicates a crank arm also a receptacle provided for the purpose. secured to the shaft for actuating the shaft A further object of the invention is the proand the pinion 14, or it will be apparent that vision of a corn sheller that is reasonable in any other means of rotating the shaft 15 may 0 cost of manufacture, is extremely durable in conbe substituted, as for instance the shaft may be 6 struction and will effectually remove the grains geared to a motor shaft (not shown). of corn from the cob. The means for stripping the grains from the A further object of the invention is the procob, and for supporting the ear of corn during vision of an improved construction of cutting the shelling operation, is a cutting element in means for separating the grains of corn from a the form of an annulus or ring designated 17, 70 corn cob including an annular cutting element and having a circumferential flange 18 to seat adapted to support the ear of corn and to permit on the top of the tubular flange 8.
